a Rose diagrams of the FSOD at six stations. b The spatial average of the polarization of a fast shear wave from shear wave splitting is calculated by weighting inversely proportional to the square of the distance from the station. The red rose diagram is normalized, and the yellow bars are the average polarization. Rose diagrams are plotted at the center of each block; blocks with fewer data than the threshold are not plotted. The background grey boxes represent the shaded topography
